The clamping member in this embodiment is arranged in the middle of the triangular support frame body to make the three vertical poles form a whole. The supporting member is a circular plate 2 formed by three pads, which are respectively arranged at both ends of the triangular support frame body. The encirclement can be achieved by a tongue-and-groove manner, and holes are opened on the pads so that the enclosed parts can be fixed to the floor. The upper circular plate supports the top building structure, and the lower circular plate supports the floor.
